After our exclusive survey revealed that one in five men suffer serious problems conceiving, today we're testing sperm, live.
When couples have difficulty getting pregnant, the focus often falls upon the woman when trying to diagnose the problem. However, in around half of these couples, male infertility plays a role.
But how would you know if you have a problem with your sperm? How can you find out how fertile you really are? Well Dr Chris is here to help along with embryologist Alpesh Doshi. They're in our This Morning sperm clinic, ready and waiting to help a queue of willing volunteers, including Craig Loomes, 29, whose wife Jennie Rose was on the show on Monday.
